The Spanish maestro faced his former club for the first time since his departure on Sunday, describing the game as "very intense and special" while thanking both the Blues and the United fans for their support.

"As always, the atmosphere in Old Trafford was spectacular. Your support this season is vital," Mata said in his weekly blog.

"It's worth mentioning the Chelsea fans in Old Trafford; their affection comforts me and, as I have said so many times, I will always feel grateful to them and to the club. I feel there is mutual respect and this is very important for me in all aspects of life.

"As you can imagine, this has been a very intense day for me. A Sunday full of emotions because of the big game against Chelsea. Facing them for the first time was special and the match, very even in my opinion, was tense until the last minute,"

"I think we had a good first half but we weren't able to take our chances. In the second half, after Drogba's goal, they took control of the game for some time but in the last stage we pushed hard and managed to equalise," Mata said.

"The truth is I felt very comfortable on the pitch and it was nice to meet again friends and former team-mates after all these months. In the end, when you are on the pitch, you concentrate on doing your job to help your team and you must be absolutely focused on that.

Mata hints United finished the game with a bittersweet taste as even though they managed to secure a point, he believes the Old Trafford club deserved more after their impressive first-half.

"In short, a point that wasn't much at half-time was celebrated and deserved at the end of the game," he said. "However, I'm sure that we will get better and better and we will climb to the main spots, where United deserves to be. My aim is to work day after day in order to help the team get to its goals.

"Another big game awaits us the next weekend, this time against our Manchester rivals."
